Subversivism is the practice of extolling certain gender and sexual expressions and identities simply because they are unconventional or nonconforming. In the parlance of subversivism, these atypical genders and sexualities are "good" because they "transgress" or "subvert" oppressive binary gender norms.

…

One of the most common targets of such critiques [not subversive enough] are transsexuals, and particularly those who are heterosexual and gender-normative post-transition. Indeed, because such transsexuals (in the eyes of others) transition from a seemingly "transgressive" queer identity to a "conservative" straight one, subversivists may even claim that they have transitioned in order to purposefully "assimilate" themselves into straight culture.

…

It is sadly ironic that people who claim to be gender-fucking in the name of "shattering the gender binary," and who criticize people whose identities fail to adequately challenge our societal notions of femaleness and maleness, cannot see that they have just created a new gender binary, one in which subversive genders are "good" and conservative genders are "bad." … So now, gender-nonconforming folks are on top and gender-normative people are on the bottom—how revolutionary!

Now, I understand the temptation for a marginalized group to turn the hierarchy that has oppressed them upside down, as it can feel very empowering to finally be atop the pecking order, but it's absurd to claim that such approaches in any way undermine that binary.
